ATOMIZER Filed March 25. 1951 Patented June le, 1932 UNETE STATES JOHN D. RODGERS, OF GRIFFIN, GEORGIA A'roMrzEn Application filed. March 23, 1931.

This invention relates to improvements in atomizers, and has for'its principal object the provision of a compact and handy article which is simple and economical to manufacture and in which compressible bulb is provided with an interior sleeve or tubular portion receiving the liquid receptacle, whereby the receptacle is held in position and protected by the close fitting sleeve against soiling or corrosion.

Further objects reside in the advantageous features of the atomizer herein described in connection with the accompanying drawing illustrating a recommended embodiment of the invention, and the improved features will be pointed out in the appended claims. It will be understood, however, that the struc tural details of the article herein described may be varied to suit particular purposes without departing from the essence of my invention.

In the drawing,

Fig. 1 is a side elevation of a preferred form of the improved atomizer; and

Fig. Qis a vertical section of Fig. 1, certain parts being shown in elevation.

In the particular embodiment chosen for the purpose of illustration7 the atomizer comprises a compressible bulb 3 of rubber or other suitably resilient material, the base l of the bulb preferably being iiat and having a tubular reentrantneck portion 5 integral with said base and extending axially within the bulb; a bottle 6 or other receptacle insertible at the bottom mouth or entrance 7 of the reentrant portion or sleeve and removably retained within said neck; and one or more tubes or conduits extending through the top of the bulb and adapted, upon compression of the bulb, to draw the liquid from the receptacle and eject it in the form of a line spray, in accordance with common practice.

The conduits of the illustrated arrangement comprise an elongate tube 8, extending downwardly through the top of the bulb and into the liquid 9 and terminating near the bottom of the bottle 6; and a relatively short tube l0 entering the of the bulb parallel to tube 8, and adapted to emit blast of air when the bulb is squeezed. rlhe outer ends Serial No. 524,519.

of said tubes may be constricted to provide relatively minute outlets, and the air blast from tube 10 is directed across the outlet of tube 8 to draw the liquid upwardly through the latter tube and spray it in a transverse direction. These tubes may be frictionally supported in a rubber nipple 11 removably held within an opening at the top of the bulb 3, er may be otherwise retained in operative relation.

It will be apparent that the particular nature of the liquid-ejecting Conduit, its complemental air exhaust or its supporting elements, are not essential to this invention; any common form or arrangement may be satisfactorily employed. Similarly, the bulb may have the usual one-way valve or vent for admitting air thereto during expansion of the contracted bulb, such for example as the normally closed base valve 12 which remains closed as the bulb is compressed but opens when it is allowed to expand.

The bottle 6 preferably has a detachable cap or cover 13 which prevents. its liquid contents from spilling into the bulb cavity, and said cover is preferably formed with an annular groove or recess receiving a complemental shoulder' or flange 11i at the inner end of the reentrant neck 5, thereby to hold the bottle against accidentalv displacement. rl`he tube S passes through the cap or closure 13 which fits tightly around the tube to prevent evaporation or escape of its liquid contents. It` will be observed that the receptacle 6 is preferably barrel shaped so that it is tightly clasped by the expanded wall of the neck 5, and that the sloping character of the bottle sides may be adequate to prevent casual displacement thercof, apart from the cooperating effect of the neck shoulder 14.

' The operation of the atomizer will be understood from the foregoing description, and it is apparent that the liquid receptacle may readily be grasped by the .lingers or by a suitable implement and drawn outwardly of the reentrantneck through its open mouth or entrance 7. l fter refilling the bottle it may again be inserted and will be gripped by the resilient wall of the neck. rlhe bottle may bel slipped olf the lower end of the tube S dur- 1 (iii ing its removal from the bulb, or the tube may be retained by the closure. 13 and drawn away from the nipple ll; and, upon replacing the bottle, the conduit may be reinserted through the nipple or bottle closure, or both, without difliculty.

It will be observed thatthe receptacle is protected against corrosion or soiling from air, gases or moisture within the bulb by reason of the surrounding and tightly fitting wall of the tubular sleeve or neck portion which preferably constitutes an integral part of the bulb. It the receptacle is made of glass or other rangible material, it is a-lso substantially protected from cracking or breaking by the circumposed, resilient bulb. The improved atomizer is compact and easy to handle, yet accommodates a receptacle of reasonable capacity and affords adequate air space in the chamber between the interior sleeve and outer wall of its bulb for emitting a forceful blast of air through its air tube when the bulb is compressed.
